JOURNAL-BOX GELLAR.

Application filed April 14, 1916.

T0 all whom it may concern:

Be it known that we, ALVIN C. MoConn and lvxn A. RANnEL, citizens of theUnited States, residing at Chicago. in the county of took and State ofillinois` have invented certain new and useful Improvements in.Journal-linx Cellars; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which. it appertains to make and use thesame.

Our invention relates to journal boxes forv car trucks. and consists ofthe novel features hereinafter described and defined in the claims.

Our invention was primarily intended to afford an improved cellar inthat type of: journal boxes disclosed and claimed, together with theprocess for mamifacturing the same, in the three prior patents to IvarA. Kandel, towit: 1,077,159, of date October 28, 1913, entitled Journalbox; 1,089,585, of date March 10, 1914, entitled Process of makingjournal boxes," and 1,090,085, of date March 10, i914. entitled Journalbox. By reference to said patents, it will be seen that the box thereindisclosed and claimed, is an all steel. box, wherein the. cellar isfirst independently made from a comparatively thin sheet of steel by theapplication of suitable dies, and is then placed in a mold and the topis cast fast thereto. The mass of the metal is in the top, and thecellar is of comparatively thin section and light weight. There are alsoother boxes, wherein the chief mass of metal is in the top, where it isneed` ed to withstand the normal strains of the service, and wherein thecellar is of compa ratively thin sectionand light weight. In someinstances, the 'cellars and tops are separately Iliade and rivetedtogether, in other instances, the tops and cellars are integral castingsannealed, or in other words, the ordinary malleable iron boxes, withextra light cellars. However. these light weight cellars may be formed,the chief strain, which they must withstand, is the one to which theyare subjected from the load, when the hoisting jack is applied thereto,to lift the box and the load for inspection and repairs; and in the caseof boxes intended for use on the arch bar type of car truck, thehoisting jack is usually applied to that part of the box outward of thetie bar seat. Modern freight cars are of large capacity,

usually 80,000 or 100,00() pounds, and the trend is toward still largercapacity,

The primary function of the cellar of a journal box is simply that of acontainer for the oil and waste; and, if it were not for this necessityof having the cellar of the requisite strength to permit the said usageof the hoisting jack, the cellar might be extremely thin and light.Because, however, of its large load, which must be lifted by the jack,it has been found a serious problem to get the requisite strength whereneeded, without ay large increase in the weight, By ouriiinvention, wesolve that problem.

VIn the accompanying drawings, the pref: ferred form of our invent-ion1s illustrated as applied to the all steel box of the type disclosed andclaimed in said Randel patents; and. in said drawings, like notationsrefer to like parts throughout. the several views.

Figure 1 is a side elevation of said box, with the lid removed; Fig. 2is a bottom plan of the san'ie; Fig. 3 is a vertical cross section onthe line .r3 .c3 of Fig. 1; and Fig. i is a front end elevation of thebox, shown in Figs. 1 and 2, with a portionbroken away.

The numeral 1 represents the cellar of pressed steel and the numeral 2the top of cast steel cast fast thereto. The top 2 is provided with anarch bar seat 3 and j'urnal bolt lugse, as in the box of the said l.andel patents. The bottom of the cellar 1 is rounded. or of arch-shapein cross section.

as best shown in Figs, 2 and 3. at all portions thereof, with theexception of that part lying in, the central zone, directly under thearch bar seat 3. At this central zone, the side joining portions,between the adjacent curi-'ed parts of `the bottom are angularlydepressed to get, on the bottom, a`y flat seat 5 for the tie bar of thetruck frame.. The bottom of the cellar 1 is also curved, or made oflarch-shape longitudr.

at the opposite ends of this lip. vrvhis mouth-lig',- d, to 'ri-'itthatpor of the.

se 1d en fn :lis ance heron' the lid opening, this portion of the front'\\ell nearly, but not quite' vertical, flaring. slightly, hutnjard, inrespect to the curved part of ,the lower forward ond o" the box, liestshown in Fig. 1, and slr. "ng at an obtuse angle-.to -tlieside Wells ofsaid' mouth opening t. Hence, this cross heom, afforded by saidmouth-lip d, isof1-eonsiderahle strength., and, in coperation with theother peculiar vfeatures of the front end of the box, ,hithertoidentified, makes the .front end of the box relatively strong, ascompared with the vertical side wells nl the cellar. To get the for!ther needed sti'eiigtli,for jacking purposes, ne provide a depressedboss a in that part of the bottoni of the cellar, outward of the tie horseat 5, locating the seine :at the crown of the arc-h, in the. forni ofthe h'ox shown; and, in addition, we. provide three depressed radialribs, -ii the .instance illustrated, one of `which is marked with thereference letter b and the other two with the reference let ter c. Thestrengthening riligb is the mein one and it extendsroin the bss aoutward andl upward Acentrally Vinthe- ;'eurr'ed forward end of thecellar end runs out or merges into the front Wall of the box, di-

reetly under the mouth-'lip or lifting boem" fd. The other two radialribs re" located opposite to each otherfand exft d frorn'said boss a,laterally outward and upward in the Curved botto-mot the Cellar and 'rimout or merge` therein,V helore the curved bottom joins with the straightside wall of the cellar.' lVhen the cellar pressed up from plete'steel,by the usage of dies', asinrthe Bandol box, the said depressed boss aand the-radial rihs and dare, of course, formed also h5' the usageor-dies of the proper shape, and the ine-tal will he ofthe same sectionor thickness as the other portionsot the said cellar. It the cellar -bea casting, the depressed boss a and radial ribs b end o will, of Course,be east integral with the other ports of the cellar and, nevertheless,

cen, if desired, be inode hollow and of the same section or thickness.as the other partsof the cellare Whether .formed in one or the other ofsaid two Ways, or however they nia-y be'ormed, it will be seen that theboss .a and the radial ribs. b and c .dis osed. as i l) shown anddeseriherhlgreatly add to the strength of the cellar, near its forwardend, without increase of its mass or' Weight; and with the forward endof-the box made strong, in the ways above. noted, the strains from thehoisting jock will he distributed to the best advantage for permittingthe Ateller to sustain such strainss Withont Crushing. .ln other words,when the hoisting jaelr applied, with. its lmovable head hearing instthe boss; a., the lifting strain will he transferred chiefly throngh thelongitudinal radial ril and the corners e to the cross' benin d and hethereby iii-st Carried to the liront end walls of the box and thondelivered to the side walls ofthe box, about .midway of their height.Uf' course, 'part of the. vstrain transferred by the radial rib f moredirectlr to the said upper half portion and theside walls of the cellar.The intervening column or lportions of the cellar wall, below the top,then receiving, the-strain so trzuisfmrred, is relatively short` asconi! pared n'ith toe entire' depth of the cellar,-

and thisl short column is Yof snficient strength to stand the stra-inand transmit the same to thetop'of the-box.

H' attempt had been inadeto use the rertical sides of the coller, as alifting column, for their full height, without any stillening orstrengthening, the-sides would dish or Y buckle and the-cellar crush,under the load. By combining with tho'speciliedfmitines of strength,naturally present at the front end of the cellar, ton'it: the cross beam(l and the corners a, the new vfeatures. herein' disclosed., towit: theboss a, and the longitudinal rib and, if need be, the radial'ril'i' e,the problem was solved. By 'actual and extensive service, it hasbeen'found that our invention, herein dislosed Aand claimed, adapts snch thinAcellars to niithstand sueeessfully the jacking strains, even when theboxes are of the largest size :ind used under loaded cars of the largestcapaeity. It will, of course, be understood that for sonie sizes ofboxes, the lateralradial rib o may he dispensed with, and that for stillother" and larger-'sized boxes, it may be desirable to add additionalradial ribs, The essential things are the boss a and thelongitudinal rihb,'or its equivalent, getting its baseof resistance in the boss (n, andextendingto o; point under the month-lip or liftingbemn d, It shouldalso be noted that there is co4 operation between the flat tie barseaitz, formed on the bottoni of the box, es de scribed, and thefeatures, above identified',

added for jacking purposes, towit: the bossa and the radial ribs Z; andc. The seid arts all cooperate to add strength to the bottoni :part ofthe cellar.

It will be understood that While the box illustrated is of arelrsha-peincross section, and also longitudinally et its forward end' portion,outwardlyio the tie har seat, and

beam, a jacking boss on its bottom, and strengthening means extendingfrom said boss forward and upward to a point directly under said beam,substantially as described.

2. A journal box cellar having a lower mouth-lip. adapted to serve as alifting beam, a jacking boss on its bottom, a strengthening ribextending from said boss forward and upward to a point directly undersaid beam, and additional strengthening means, in the bottom,cooperating with said boss and rib, substantially as described.

3. A journal box cellar having a lower mouth-lip, adapted to serve as alifting beam, a jacking boss on its bottom, outward of its longitudinalcenter, a strengthening rib extending from said boss forward and upwardto a point directly under said beam, and additional strengthening ribsextending radially from said boss in the bottom of the box,substantially as described.

4. A journal box cellar having a lower mouth-lip, adapted to serve as alifting beam, a jacking boss on its bottom, outward of its longitudinalcenter, a strengthening rib extending from said bosspforward and upwardto a point directly under said beam, and two opposite radialstrengthening ribs extending from said boss laterally outward across thebottom of the box, substantially as described.

5. A journal box cellar of arch-shape in cross section and also at itsforward end below the lid opening, and having a mouth-lip,

adapted to serve as a lifting beam, a jacking boss at the crown of thebottom and three radial ribs extending therefrom, one forward and upwardto av point under said beam and the other two laterally outward in thebottom of the box, substantially as described.

6. A journal box cellar havin a rounded or archshaped bottom providewith a depressed jacking boss, at the crown of the arch, substantiallyas described. l

7 A journal box cellar having a rounded or arch-shaped bottom providedwith a depressed jacking boss, at the crown of the arch, outward of thetie bar seat, substantially as described.

8. A journal box cellar having a rounded bottom and provided withangular depressions on the opposite sides of its interme diate roundedportion, which depressions ai'ord a flat bearing for the tie bar, thebottom of said cellar, outward of said angular depressions having adepressed boss and depressed ribs radiating therefrom, the one towardthe outer end of the box and the other two toward the sides of the box,substantially as described.

In testimony whereof we aflix our signatures in presence of twowitnesses.
